' This invention relates to hoistingimechanism, and particularly to an improved con-. struction especially adapted as an automobile transmission hoist, the object being to provide an improved construction which may be disassembled and then assembled in posi- .311s then placed in the base 1 where it is held by friction with its lower end resting on tion preparatory to raising or lowering an'automobile transmission or some other part of an automobile or other machine.

Another object of the invention is toprovide a hoist which may be used in connection with inserting or removing a transmission for an automobile, wherein after the foot boards of the automobile have been removed, the base of the hoist may be arranged at a desired position, and then the other parts mounted thereon ready fo'r use, the structure; being such that the parts may be disassem- 4 bled and removedpiece by piece after having functioned in the desired manner;

In the accompanyingdrawings' Figure 1 is a side view of a hoist disclosing an embodiment of the invention, the same be ing shown in connection with the transmis-" v 7 7 cable may bepulled for elevating the pulley sion of an automobile. 7

In automobiles and other machinery, it is place while being. bolted or otherwise secured properly and permanently in position. In the case of a transmission of an automobile, it is extremely difficult to hold the parts i 6 in place while applyingthe proper bolts and chinerylin place, an improved formof hoist parts in place while thechief mechanic does. the work of connecting u'pflthe parts. To avoid this double use of workmen, and to properly hold the transmission orother piece of ma-' then-reassembled in the position. in which it is to be used.

In the case of an automobile transmission, the floor boards are taken up and then the base-'1 arranged to a desired point below and near the transmission 2. The standard a suitable set screw Arranged above the O collar 4 is an arm 6 slidingly and swingably mounted on the standard Thisarmis provided with ahook 7 at the outer end and ahook 8 ,intermedi atethe ends.

WVhen it is desired to hold the transmission 2 and other 1 parts in a certain position, wedge is inserted as shown in Figure 1 and the parts are held in proper position without the necessity of tying the end of cable 9. In case of removing a transmission after the hoist has been placed in position near the transmission as above described, and the transmission disconnected and lowered, the hoist may be left in that position until the transmission has been repaired or inspected, and then the hoist may be utilized for raising the transmission March A.

and holding the same in proper position to be accurately and easily bolted or otherwise secured 1n its correct operating position. After I the transmission has been properly connected up, wedge 20 is released and hook 13 disengaged from cable 14. Cable 14 is then removed. After this has been done, the link 16 is disengaged from hook 17 and arm 6 slid off of the standard 3. These parts are moved to a distant point and then the standard 3 is lifted out of base 1 and moved to a distant point. Base 1 is then removed and the hoist is disassembled and ready to be assembled in a new position for functioning as a hoist. The fact that the parts are readily capable of being assembled and disassembled and adjusted so that the arm 6 may be high or low, permits the hoist to be used in what may be termed diflicult places, and where ordinary I hoisting means could not possibly be used.

In using'thedevice described many uses may be found therefor, but it is particularly adapted for machinery and especially transmission hoists. As shown in the drawing, the invention is presented as a hoist for automobile transmissions and other objects with the framework so constructed that it may be disassembled and reassembled through part of an automobile afterthe floor boards have been removed or through any other object like different kinds of machinery where lifting or lowering'is necessary.

I What I claim is:

. A hoistfor automobile transmissions and other objects, including a supporting standard and arm, a pulley structure carried by said arm, a pulley structure carried by said standard, a: pulley structure adapted to be connected with the transmission to be lifted,

a cable extending through all of said pulley structures and connected at one end with said arm whereby when the cable is pulledin one direction said transmission will be raised, the pulley structure carried by said arm having a solid frame with a passage-way above the cable extending therethrough, a wedge positioned in the passageway, and means connect-
